2825.90.20.00 - Tin oxides

This category, HTS 2825.90.20.00, specifically covers tin oxides. These are inorganic compounds of tin, typically in an oxidized state. This designation is used for various forms of tin oxides, which can vary in their chemical composition (e.g., stannous oxide, stannic oxide) and physical form (e.g., powder, crystalline). Their primary utility is often as raw materials in the manufacturing of ceramics, glass, pigments, and as catalysts.

It is important to distinguish tin oxides from their sibling categories. For instance, 2825.90.10.00 refers to beryllium oxide and hydroxide, while 2825.90.15.00 is for niobium oxide, and 2825.90.30.00 pertains to tungsten oxides. Similarly, 2825.90.75.00 is for cadmium oxide, and 2825.90.90.00 encompasses all other remaining metal oxides, hydroxides, and peroxides not specifically enumerated elsewhere in this heading. Therefore, the critical distinguishing factor is the presence of tin as the primary metallic element in the oxide compound.

As a leaf node, HTS 2825.90.20.00 does not have further subdivisions. Classification within this code relies on the definitive presence of tin in the oxide form. If a product contains tin and exhibits characteristics of an oxide, and is not more specifically classified elsewhere, it will fall under this heading. Examples might include refined tin dioxide used in polishing compounds or various grades of tin oxides employed in specialized industrial applications.
